Attention, for example, can help in selectively encoding items into visual memory. Attention appears to be able to alter things previously recorded in visual memory; signals that occur long after an array of objects has been presented can affect memory for those objects (Griffin & Nobre, 2003). This "attended-to" effect occurs because the more attention that is paid to an item, the better it is remembered. Conversely, if attention is divided among several items, then only those items not enough to capture attention will be remembered.
It has also been shown that remembering specific details about an event requires attention. For example, if you are asked to remember what movie you saw last night, you would probably not remember everything about the plot or the actors, but rather what scenes were important to remember. Your ability to remember specific details about the movie depends on which parts of its representation in your mind's eye get captured by that experience. The more attention you pay to a movie, the more likely you are to remember aspects such as scenes or characters instead of the overall plot.
Finally, attention may also play a role in allowing us to store information in memory for later use. If you are reading this article, then you are obviously paying attention and using the information stored in it.
Attention allows us to select which elements of our environment to record in memory and which ones to ignore.
Cueing attention after visual stimulus disappears biases which objects are remembered best. Historically, this discovery has been attributed to the impact of attention on memory rather than subjective visual perception. However, recent work has shown that attention also influences sensory processing and thus may be able to modulate neural activity before it reaches awareness.
Retrospective attention allows us to remember what happened earlier in time by focusing on cues that signal the presence of a past event (flashbulb memories). It has been demonstrated using both behavioral and neuroimaging methods that observers can better recall the location or identity of stimuli they attended recently than those they did not attend. This phenomenon has been termed "retroactive attention" because it involves attending to information after it has occurred.
Attention also affects which events we perceive. In other words, it filters out irrelevant information so that only relevant data reach our consciousness. This process is called "informational suppression". Research has shown that if one item in a sequence is task-relevant, then participants will fail to report otherwise visible items in the same sequence as long as these items are ignored using an irrelevant cue (e.g., another sequence of items) - even if the two items are closely spaced in time.
In addition to these two types of attention -- perceptual and retrospective -- there is also anticipatory attention.
For starters, memory has a limited capacity, so what is encoded is determined by attention. Although the role of attention in the production of unconscious memories is more complex, division of attention during encoding precludes the generation of conscious memories.
Also, attention plays a key role in retrieving memories. Without attention, you would not be able to recognize or respond to things that happen around you. Attention allows your brain to filter out unnecessary information so that you are aware of only those things that matter right now. This is why it is important to pay attention when learning something new or trying to remember something old.
As you get older, your ability to pay attention declines. This is because aging brains experience loss of neurons that are essential for focusing attention on one thing at a time. As these neurons die, it becomes harder for you to ignore distractions and concentrate on what you need to learn or remember.
Last, but not least, attention affects how easily you can store memories. The better you pay attention, the easier it will be to encode new information into memory and the faster you will be able to retrieve it later.
Thus, attention is crucial for maintaining good memory skills. It allows you to select which memories to preserve and which ones to discard. If you fail to pay attention, you will lose the ability to recall memories from past events.
When describing the selective regulation of attention, factors such as spatial closeness, signals that change the spatial scope of attentional focus, prominence of targets and distractors, and perceptual grouping between the target and the distractors should be considered. Spatial proximity is an important factor in determining how much each item influences the selection process. If two items appear close together, they will likely be processed simultaneously or within a short time period. Items that are far apart from one another may be processed at different times if enough time passes between them.
Attention can be focused on only certain parts of the total sensory input. This selectivity allows us to pay attention to something specific while ignoring other things. Selective attention can be divided into two categories: feature-based selection and goal-based selection. Feature-based selection occurs when the brain selects which stimuli it will attend to by looking at their physical properties (i.e., color, shape, etc.) Goal-based selection happens when the brain decides what to attend to based on its current needs/goals (i.e., listening for threats in your environment when you go hiking alone at night).
Distractibility is the ability of some elements in our environment to capture and hold our attention even when we intend to devote our full attention to another element. Distraction can come in many forms including sounds, images, touch, and taste.
Attention is essential for many elements of learning and memory preservation. When you learn something, you encode the knowledge, which needs focus. However, memory recall needs attentiveness as well. As a result, paying close attention is essential.
There are two forms of attention: focused and divided. Focused attention is required when learning or recalling specific information. This type of attention requires concentration so that relevant details are taken into account while other aspects are ignored. Divided attention is needed when performing multiple tasks simultaneously. It involves giving equal priority to each task without being distracted by others. For example, if you are driving a car and trying to remember where you left your keys, you are using divided attention.
Attention has a limited supply; therefore, it must be allocated carefully between different stimuli or events. If too much attention is paid to one thing, this will limit the amount that can be given to others. For example, if you are studying for an exam and pay too much attention to what is happening around you, then you won't be able to memorize as much information as you could otherwise.
Attention also affects how easily we learn new things. If we are distracted by something else when learning something new, it can make it more difficult to remember later. This is because attention helps us filter out unnecessary information so that only relevant facts are stored in memory.
